The paper presents an analysis of the state and possibilities of using power electronics and electric drives on ships, and in particular, in ship engine room. Problems related to the operation of power electronics in the soft network are presented. The issues related to the design of multi-pulse high power rectifiers are discussed, which is one of the most popular power electronics devices used on vessels. Then a simulation study of selected rectifier circuits was carried out. The purpose of this study was to show the effect of selecting a power electronics design on the waveforms of the voltages and currents in a soft network on the rectifier example. Also discussed are main electromagnetic device problems and issues related to regulations and recommendations for their design and operation. Proper selection of the type of the power supply design and observance of the rules and regulations ensures the efficiency of the equipment and the quality of the energy being processed and reduces their negative impact on the remaining equipment and network.

W artykule przedstawiono analizę stanu i możliwości wykorzystania urządzeń energoelektronicznych i napędów elektrycznych na statkach. Omówiono zagadnienia związane z projektowaniem wielopulsowych prostowników dużej mocy, które stanowią jedno z bardziej popularnych urządzeń energoelektronicznych stosowanych na jednostkach pływających. Przedstawiono problemy związane z eksploatacją urządzeń energoelektronicznych w sieci miękkiej. Następnie przeprowadzono badanie symulacyjne wybranych układów prostowników. Celem badania było pokazanie na przykładzie prostownika, konsekwencji wyboru konstrukcji urządzenia energoelektronicznego na przebiegi napięć i prądów w sieci miękkiej. Ponadto omówione zostały problemy dotyczące urządzeń elektromagnetycznych oraz zagadnienia związane z przepisami i zaleceniami dotyczącymi ich projektowania i eksploatacji. Właściwy dobór konstrukcji urządzania energoelektronicznego danego typu oraz przestrzeganie zasad i przepisów zapewnia zwiększenie sprawności urządzeń i jakości przetwarzanej energii oraz obniża ich negatywny wpływ na pozostałe urządzenia i sieć.

This paper presents the concept of topologies and investigation results of switched-capacitor voltage multipliers designed for application in high power systems. The analyzed family of multilevel converters includes established topologies as well as novel concepts. The application of thyristors as well as the invention of novel concepts of multiplier topologies and appropriate control make it possible to achieve high efficiency, high voltage gain, reliable and simple DC-DC converters for high power systems. Based on analytical models of the SCVMs, the paper presents a discussion of the selection of components and the efficiency of the converters as a function of converted power as well as the voltage range on the input and the output side. The results are supported by computer simulations and demonstrative experimental tests.
